The process of files being corrupted owing to some hardware or software failure is referred to as data corruption and this is one of the main problems which hosting companies face as the larger a hard disk is and the more info is filed on it, the more likely it is for data to get corrupted. There are various fail-safes, yet often the info becomes damaged silently, so neither the file system, nor the admins detect a thing. Consequently, a corrupted file will be handled as a regular one and if the hard disk is a part of a RAID, that particular file will be copied on all other drives. In principle, this is done for redundancy, but in practice the damage will get even worse. The moment a given file gets damaged, it will be partly or fully unreadable, which means that a text file will no longer be readable, an image file will display a random blend of colors if it opens at all and an archive will be impossible to unpack, so you risk losing your site content. Although the most widespread server file systems have various checks, they quite often fail to find a problem early enough or require a long amount of time in order to check all files and the web hosting server will not be operational for the time being.

No Data Corruption & Data Integrity in Cloud Web Hosting

The integrity of the data which you upload to your new cloud web hosting account will be guaranteed by the ZFS file system which we make use of on our cloud platform. Most internet hosting service providers, like our firm, use multiple hard disks to store content and since the drives work in a RAID, the same information is synchronized between the drives all of the time. When a file on a drive is corrupted for some reason, however, it is very likely that it will be reproduced on the other drives since other file systems do not feature special checks for that. In contrast to them, ZFS applies a digital fingerprint, or a checksum, for every single file. In the event that a file gets damaged, its checksum won't match what ZFS has as a record for it, and the damaged copy shall be substituted with a good one from a different disk drive. Because this happens immediately, there is no risk for any of your files to ever get damaged.

No Data Corruption & Data Integrity in Semi-dedicated Servers

Your semi-dedicated server account will be shielded from silent data corruption as all of our storage servers make use of the innovative ZFS file system. What makes the latter unique is that it employs checksums, or digital identifiers, to verify the integrity of each file. When you upload content to your account, it'll be stored on a couple of redundant drives being employed in a RAID i.e. the files will be the same on all drives. All copies of a given file will have the same checksum on all hard disks and ZFS will compare the checksums of the duplicates quickly, and if it finds a mismatch, that will indicate that one of the copies is damaged, it will substitute that file with a healthy copy from one of the other drives. Even if there is an unexpected power failure, the data on the servers will not be corrupted and there won't be any need for a time-consuming system check which other file systems perform after some malfunction, prolonging the time needed for the server to go back online. ZFS is the sole file system that can really protect your content from silent data corruption.
